Yes
Depends on what the felon was charged with.
(in the US) The degree of the crime is determined by the value of the item stolen, and whether or not it crosses the value line into being a felony offense. There is no specific criminal charge for theft of a firearm, unless a felon (or convicted felon) happens to be the one that steals it. Then the penalty is enhanced by the fact that this is a convicted felon in possession of a firearm.
Maybe - maybe not. If the gun was involved in a violent felony and you are in possession of it, yes, you could be charged with that violent felony. Even being IN a car with a gun places you in, what is called, "concurrent possession" of that gun.
No, not in the US. Under Federal law you cannot be in possession of a firearm. All states have separate prohibitions for felons being the police.
No.
A felony does not go away unless the conviction is expunged from your record by govt. officials. Because of this, it doesn't matter how long ago you were convicted of a felony, owning, purchasing, or being in possession of a firearm is illegal.
No.
No. The law against being a felon in possession of a firearm is a federal law.
Disabled people aren't exempt from going to prison. Being a felon in possession of a firearm is a federal felony.. that's hard time in any state.
No. Convicted felons are prohibited from being "in possession" of a firearm. The law considers proximity to a firearm as being "in possession." STAY WAWAY FROM THEM unless you want to look at the possibility of another 15 years in federal prison.
What card? Was it stolen? If it was stolen and you had it in your possession, and you knew it was someone else's and not yours - whether you used it or not you are guilty of being in "possession of stolen property."
If there is weapon in the home she is in grave danger of being charged with "possession" of a firearm, and YOU could also be charged as an accessory for knowingly allowing her to have access. It is NOT necessary to actually have the firearmn ON youir person to be charged with possession, mere 'ready access' to it serves as the prohibiting factor.
